Why? What kind of RV battery sensor? Voltage? Hall sensor or shunt? Batteries don't do much. They accept charge and dispense power...

That is what the manufacturers state in their warnings. But...

So all 3 batteries are located together, right? How are the 2/0 wires for the 10ft run connected to the battery bank? Both + and -...

+1, good question. If you try to charge just 1 battery, does it charge at 5A or 10A? If 5A, that sounds like battery limited. If 10A...

You are the BMS. Hopefully you are attentive. You're fired as a BMS. (and as a battery builder) How many Ah are the cells/battery...

What is the battery chemistry? Lithium has a far greater ability to deliver a LOT of current so the more isolation, the better.

3000W / 20V inverter cutoff / .85 efficiency = 176A A 175A fuse is on the edge of blowing at operating current. If you get a nuisance...

You need to put a number value on "only occasionally" and "only when needed". Typically, RV air conditioners come in 13,500 or 15,000...

2 x (16 x300W) = 9600W

Not enough info to answer. Are your systems identical equipment? Are the battery charge states and loads identical?

The BMS settings are battery protection values (max, min voltage, max current…). The SCC settings are for setting your charge...

Should still be 200Ah at 24V.

Yikes, that’s not right! Can you post pictures?

Just sand it flat and bolt to it like it is, there's still enough contact area.

You should start a new thread with this info. Feel free to ping me with an @MisterSandals mention so I find it. Currently traveling...

2C is 200A per 100Ah battery or 800A total. I mentioned .2C which is a conservative LFP charge and discharge number.

100Ah x 4 = 400Ah 400Ah x .2C = 80A 1000W / 58V charging voltage = 17A You could max out your 150/35 and your batteries could handle...

This is battery voltage, independent of your solar panel voltage. As set in your pic, when 59.90V battery is detected, a disconnect...

And thank you! This is my second outing trying to get this worked out. I’ve been out here since 530 this morning. Did I mention it’s...

Set it to what your batteries can handle.
